+### Initial Setup
+At DLS, first enable `docker compose`:
 ```bash
+# this command must be run every time you want to use compose in a new shell
 module load docker-compose
-ln -s /usr/bin/podman ~/bin/docker
+
+# the remaining commands need only be run once
+
+# these steps will make cli completion work for zsh
+mkdir -p ~/.oh-my-zsh/completions
+podman completion zsh > ~/.oh-my-zsh/completions/_podman
+
+# these steps will make cli completion work for bash
+mkdir -p ~/.local/share/bash-completion/completions
+podman completion bash > ~/.local/share/bash-completion/completions/podman
+```
+
+### Local Developer Environment
+To launch a development environment on a workstation, including phoebus:
+```bash
+alias ec='podman compose' # just for convenience
+export COMPOSE_PROFILES=develop UIDGID=0:0 EPICS_CA_ADDR_LIST=127.0.0.1
+ec up --detach
 ```
+(UIDGID should be 0:0 for `podman` or your user id/gid for `docker`)

 ```bash
-docker compose --profile deploy up --detach
+podman compose --profile deploy up --detach
 ```
 
 or for a multiple server repo:
 ```bash
-docker compose --profile deploy -f my_server_01.yml up --detach
+podman compose --profile deploy -f my_server_01.yml up --detach
